Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, there have been enormous advances in our understanding of the neural mechanisms of selective attention at the network as well as the cellular level. The Oxford Handbook of Attention brings together the different research areas that constitute contemporary attention research into one comprehensive and authoritative volume. In 40 chapters, it covers the most important aspects of attention research from the areas of cognitive psychology, neuropsychology, human and animal neuroscience, computational modelling, and philosophy. The book is divided into 4 main sections. Following an introduction from Michael Posner, the books starts by looking at theoretical models of attention. The next two sections are dedicated to spatial attention and non-spatial attention respectively. Within section 4, the authors consider the interactions between attention and other psychological domains. The last two sections focus on attention-related disorders, and finally, on computational models of attention. Aimed at both scholars and students, the Oxford Handbook of Attention provides a concise and state-of-the-art review of the current literature in this field.

Available in PDF, EPUB and Kindle. Book excerpt: In the late-1980s, visual cognition was a small subfield of cognitive psychology, and the standard texts mainly discussed just iconic memory in their sections on visual cognition. In the subsequent two decades, and especially very recently, many remarkable new aspects of the processing of brief visual stimuli have been discovered -- change blindness, repetition blindness, the attentional blink, newly-discovered properties of visual short-term memory and of the face recognition system, the influence of reentrant processing on visual perception, and the surprisingly intimate relationships between eyeblinks and visual cognition. This volume provides up-to-date tutorial reviews of these many new developments in the study of visual cognition written by the leaders in the discipline, providing an incisive and comprehensive survey of research in this dynamic field.
Download or read book The Neuropsychology of Attention written by Ronald A. Cohen and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been 15 years since the original publication of Neuropsychology of Attention. At the time of its publication, attention was a construct that had long been of theoretical interest in the field of psychology and was receiving increased research by cognitive scientists. Yet, attention was typically viewed as a nuisance variable; a factor that needed to be accounted for when assessing brain function, but of limited importance in its own right. There is a need for a new edition of this book within Neuropsychology to present an updated and integrated review of what is know about attention, the disorders that affect it, and approaches to its clinical assessment and treatment. Such a book will provide perspectives for experimental neuropsychological study of attention and also provide clinicians with insights on how to approach this neuropsychological domain.
Download or read book Neuroscience driven Visual Representation written by Teng Li and published by Frontiers Media SA. This book was released on 2024-08-14 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual representation learning enables computers or systems to simulate the function of retinas, optic nerves, and visual cortex in the human brain, and derive meaningful information from digital images, videos, and other visual inputs. To learn the effective presentation of visual data is essential for many computer vision and artificial intelligence applications ranging from energy and utilities to manufacturing and automotive. Current popular deep learning-based visual representation learning methods do not fully consider the nature of the biological visual nervous system and are lack in interpretability. To solve visual representation well, the integration of psychological or neuroscientific approaches is required to enhance the cognition of visual data.
Download or read book Temporal Dynamics of Endogenous and Stimulus driven Attention written by Amy Leah Daitch and published by . This book was released on 2014 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective attention allows us to filter out irrelevant sensory information in the environment and focus neural resources on information relevant to our current goals, while being able to flexibly shift our focus to potentially rewarding or harmful stimuli. Functional brain imaging studies have identified networks of broadly distributed brain regions that are recruited during goal-driven attention (i.e. based on internal expectations or goals) and/or stimulus-driven attention (i.e. driven by salient or unexpected stimuli); however, the dynamics by which these networks enable selection of attended sensory information are not well understood due to the low temporal resolution of functional neuroimaging. Here, we first used functional MRI to localize attention-related and other task-relevant and -irrelevant brain networks in human epileptic subjects, prior to localization of their seizure foci using electrocorticography (ECoG), electrodes placed directly on the cortical surface. We subsequently recorded cortical physiology from the ECoG electrodes during a spatial attention task, involving both goal-driven and stimulus-driven attention, and co-registered electrode positions with the fMRI-defined networks to study network-specific dynamics during these two processes. We found that low frequency local field potential (LFP) oscillations, which are thought to reflect fluctuations in local neuronal excitability, became selectively phase modulated over task-relevant brain regions/networks during the same task epochs in which they are recruited in fMRI. This mechanism may alter the excitability of task-relevant regions or the effective connectivity between them to enable selective neural processing of attended stimuli. Furthermore, different attention processes (holding vs. shifting attention) were associated with phase modulations at different frequencies, possibly to multiplex different cognitive processes and minimize unnecessary cross talk between unrelated neuronal populations.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of modern neurobiological methods over the last three decades has provided overwhelming evidence that it is the interaction of genetic factors and the experience of the individual that guides and supports brain development. Brains do not develop normally in the absence of critical genetic signaling, and they do not develop normally in the absence of essential environmental input. The key to understanding the origins and emergence of both the brain and behavior lies in understanding how inherited and environmental factors are engaged in the dynamic and interactive processes that define and direct development of the neurobehavioral system. Neural Plasticity and Cognitive Development focuses on children who suffered focal brain insult (typically stroke) in the pre- or perinatal period which provides a model for exploring the dynamic nature of early brain and cognitive development. In most, though not all, of the cases considered, the injuries affect substantial portions of one cerebral hemisphere, resulting in patterns of neural damage that would compromise cognitive ability in adults. However, longitudinal behavioral studies of this population of children have revealed only mild cognitive deficits, and preliminary data from functional brain imaging studies suggest that alternative patterns of functional organization emerge in the wake of early injury. Neural Plasticity and Cognitive Development posits that the capacity for adaptation is not the result of early insult. Rather, it reflects normal developmental processes which are both dynamic and adaptive operating against a backdrop of serious perturbation of the neural substrate.
Download or read book Attention predictions and expectations and their violation attentional control in the human brain written by Simone Vossel and published by Frontiers Media SA. This book was released on 2015-05-20 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the burdened scenes of everyday life, our brains must select from among many competing inputs for perceptual synthesis - so that only the most relevant receive full attention and irrelevant (distracting) information is suppressed. At the same time, we must remain responsive to salient events outside our current focus of attention - and balancing these two processing modes is a fundamental task our brain constantly needs to solve. Both the physical saliency of a stimulus, as well as top-down predictions about imminent sensations crucially influence attentional selection and consequently the response to unexpected events. Research over recent decades has identified two separate brain networks involved in predictive top-down control and reorientation to unattended events (or oddball stimuli): the dorsal and ventral fronto-parietal attention systems of the human brain. Moreover, specific electrophysiological brain responses are known to characterize attentional orienting as well as the processing of deviant stimuli. However, many key questions are outstanding. What are the exact functional differences between these cortical attention systems? How are they lateralised in the two hemispheres? How do top-down and bottom-up signals interact to enable flexible attentional control? How does structural damage to one system affect the functionality of the other in brain damaged patients? Are there sensory-specific and supra-modal attentional systems in the brain? In addition to these questions, it is now accepted that brain responses are not only affected by the saliency of external stimuli, but also by our expectations about sensory inputs. How these two influences are balanced, and how predictions are formed in cortical networks, or generated on the basis of experience-dependent learning, are intriguing issues. In this Research Topic, we aim to collect innovative contributions that shed further light on the (cortical) mechanisms of attentional control in the human brain. In particular, we would like to encourage submissions that investigate the behavioural correlates, functional anatomy or electrophysiological markers of attentional selection and reorientation. Special emphasis will be given to studies investigating the context-sensitivity of these attentional processes in relation to prior expectations, trial history, contextual cues or physical saliency. We would like to encourage submissions employing different research methods (psychophysical recordings, neuroimaging techniques such as fMRI, MEG, EEG or ECoG, as well as neurostimulation methods such as TMS or tDCS) in healthy volunteers or neurological patients. Computational models and animal studies are also welcome. Finally, we also welcome submission of meta-analyses and reviews articles that provide new insights into, or conclusions about recent work in the field.

Download or read book The New Handbook of Multisensory Processing written by Barry E. Stein and published by MIT Press. This book was released on 2012-06-01 with total page 841 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembles and their behavioral, perceptual, and cognitive correlates. The New Handbook of Multisensory Processing synthesizes the central themes in this rapidly developing area, reports on current findings, and offers a blueprint for future research. The contributions, all of them written for this volume by leading experts, reflect the evolution and current state of the field. This handbook does more than simply review the field. Each of the volume's eleven sections broadly surveys a major topic, and each begins with a substantive and thought-provoking commentary by the section editor that identifies the major issues being explored, describes their treatment in the chapters that follow, and sets these findings within the context of the existing body of knowledge. Together, the commentaries and chapters provide an invaluable guide to areas of general agreement, unresolved issues, and topics that remain to be explored in this fast-moving field.
Download or read book Attention and Time written by Kia Nobre and published by . This book was released on 2010 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our ability to attend selectively to our surroundings - taking notice of the things that matter, and ignoring those that don't - is crucial if we are to negotiate the world around us in an efficient manner. Several aspects of the temporal dimension turn out to be critical in determining how we can put together and select the events that are important to us as they themselves unfold over time. For example, we often miss events that happen while we are occupied perceiving or responding to another stimulus. On the other hand, temporal regularity between events can also greatly improve our perception. In addition, our perception of the passage of time itself can also be distorted as while we are performing actions or paying attention to different aspects of the environment. Surprisingly, this fascinating and fundamental interplay between ' attention' and 'time' has been relatively neglected in the psychology and neuroscience literatures until very recently. Attention & Time is the first book to address this foundational topic, bringing together several intriguing and hitherto fragmented findings into a compelling and cohesive field of enquiry. The book contains thirty-one critical-review chapters from internationally recognised experts in the field, carefully organised into three stand-alone, yet extensively cross-referenced, themed sections. Each section focuses on distinct ways in which attention and time influence one another. These sections, each encompassing a range of methodologies from classical cognitive psychology to single-cell neurophysiology, provide functionally unifying frameworks to help guide the reader through the many various experimental and theoretical approaches adopted. Section 1 considers variations of attention across time, and explores how attentional allocation is limited by very short or very long intervals of time. Section 2 describes several types of temporal illusion, illustrating how attention can modulate the perception of the passage of time itself. "A watched pot never boils" and, conversely, "time flies when you're having fun" nicely capture the experimental observation that the degree of attention allocated to stimulus timing contributes to its subjective duration. Finally, Section 3 examines how attention can be directed in time, to predictable or expected moments in time, so as to optimise behaviour. Bringing conceptually discrete, yet functionally related, fields of temporal attention research together within a single volume, this book provides a comprehensive overview that will be of value to the interested novice in cognitive neuroscience, whilst also inspiring experts in the field to make, perhaps previously overlooked, links with their own field of research.
